Has any one seen this: client restore mounting copy storage pool tape volumes?
November 16, 2017 09:59AM
Folks:
TSM Server 7.1.7.200 running on Linux x86_64 (Red Hat 6.8)
TSM client 7.1.6.0 running on what appears to be Red Hat 5.7 (kernel 2.6.18-300.el5)

Local system admin is performing a BMR on a system that has been backing for years to the same TSM node. So there are a lot of old files being pulled down.

What is puzzling me is that the session associated with the restore just mounted a volume from our copy storage pool:

tsm: ADSM7>select * from sessions where session_id=179758

SESSION_ID: 179758
START_TIME: 2017-11-16 11:00:50.000000
COMMMETHOD: Tcp/Ip
STATE: MediaW
WAIT_SECONDS: 2933
BYTES_SENT: 10329945
BYTES_RECEIVED: 883
SESSION_TYPE: Node
CLIENT_PLATFORM: Linux x86-64
CLIENT_NAME: NASH01.SERVERFARM.CORNELL.EDU
OWNER_NAME:
MOUNT_POINT_WAIT:
INPUT_MOUNT_WAIT:
INPUT_VOL_WAIT: ,141013,225
INPUT_VOL_ACCESS: ,250152,740: ,/adsm7T20/T037,2678
OUTPUT_MOUNT_WAIT:
OUTPUT_VOL_WAIT:
OUTPUT_VOL_ACCESS:
LAST_VERB: MediaMount
VERB_STATE: Sent
FAIL_OVER_MODE: No

Current mounted volumes includes:
11/16/2017 11:39:39 ANR8337I LTO volume 250152 mounted in drive DRIVE8503 (/dev/rmt.e203.0.0). (SESSION: 179758)

Which is a copy storage pool volume. Fortunately, we had drives available and the volume mounted so sys admin isn’t seeing a delay.

Not seen this before, not sure what the condition would be to have server reach to copy storage pool to get data.

Has anyone seen/experienced this?

Thanks!
